Tech didn't cause this, homeowners did. If it didn't have a high paying industry you'd see blight and disinvestment instead, as you're only left with retirees who don't care about that stuff.
Seattle has unusually good building codes (single-stair is allowed) but no income tax, so in that way it might not benefit from tech as much.
